It happened around 11am in the 9700 block of West Cypresswood at Cutten.
The driver of the truck apparently lost control. The vehicle left the roadway, ran up onto the grass and went through a fence and some bushes.
The maintenance employee was working on shrubs outside the complex and was hit by the truck before it crashed into the side of the building.
According to the Harris County Sheriff's Office, the driver may have had a heart attack. He was taken to an area hospital in critical condition.
The maintenance worker was also hospitalized, but in unknown condition. We're told that person is stable.
